Abstract: 1287676 Clips and clamps TECHNIAIR SA 17 July 1970 [1 Aug 1969] 34707/70 Heading E2B [Also in Division F2] A ventilating pipe of polygonal cross-section has adjacent end portions 1, 2, Fig. 1, formed with backwardly bent flanges 1a, 2a which together make a seat for a gasket 4, the flanges being held together by a clip or clamp 5. As shown, a clip 5 is used, before assembly the arms 6 of the clip being separated by a part 4a, Fig. 2, of the gasket 4. The clip 5 is placed astride the abutted flanges 1a, 2a, and the gasket part 4a pushed towards its seat 3 by a tool (12), Fig. 3 (not shown), introduced between and pulled through the arms 6 of the clip 5. The lower end 7 of the clip arms 6 then latch themselves behind the pipe flanges 1a, 2a. Alternatively, Fig. 4 (not shown) the ends of the gasket 4 can be pulled to remove it from between the clip arms and permit latching. An alternative tool inserted between the clip arms 6 has interengaging toothed bars (14, 15), Figs. 5a, 5b (not shown), which when slidden axially relatively to each other, are cammed apart to force the gasket 4 towards its seat between the pipe flanges 1a, 2a. In a further modification, holes (16), Fig. 6 (not shown), can be provided in one of the clip arms 6 to allow insertion of a tool to push the gasket 4 down. The arms 6 of the clip 5 may alternatively be kept apart before applying to the pipe flanges 1a, 2a by a short strut (19), Fig. 7a (not shown), displaced by pushing the clip home, Fig. 7b, to effect latching. The clip 5 may be secured on the pipe flanges 1a, 2a by a nut and bolt (21), Fig. 8 (not shown), parallel to the axis of pipe, or by an additional clip (22), Fig. 9 (not shown), grasping its arms 6. Alternatively, the top, closed end of the clip 5 may be made relatively rigid by forming it in a rectangular cross-section (23), Fig. 10 (not shown). In another embodiment, the clip is replaced by a thin metal sheet 26, Fig. 11, laid across the gasket 24 seated between the pipe flanges 25, its ends (26a), Figs. 12b, 12c (not shown), being bent behind the pipe flanges. A U-shaped stiffener 27 is then secured transversely across the pipe by spot welds, &c 28.

Abstract: A process for the production of organic compounds containing at least one carboxylic acid group comprises oxidising in the liquid phase a compound selected from alkyl or haloalkyl aromatic hydrocarbons; alkyl heterocyclic compounds of aromatic character; aromatic hydrocarbons containing at least one partially oxidised residue of an alkyl or haloalkyl group; direct derivatives of the last mentioned class of compounds; other aromatic compounds containing oxygen in at least one aliphatic chain; any of the compounds mentioned above substituted by at least one polar group resistant to oxidation as defined below; aliphatic and alicyclic hydrocarbons; aldehydes and halogenated aldehydes; cyclic ketones; ethers and halogenated ethers; the oxidation being carried out by p  means of molecular oxygen or ozone in the presence as catalyst of at least one bromide of a metal of variable valence, especially the mixed bromides of manganese and cobalt, the reaction being carried out in a reactor fabricated of or surfaced with a silicon iron alloy containing 13-15% by weight of silicon.  These alloys, containing also carbon, manganese and possibly molybdenum as minor constituents, may also be used in the ancillary equipment., e.g. condensers, and are found to have a corrosion rate of less than 0,1 mm./year under the reaction conditions.  The actual oxidation is carried out in a known manner, e.g. in the presence of an aliphatic or aromatic acid as solvent. The oxidation-resistant polar groups which may be present in the reactants are halogen, -NO2-SO2 NR1 R2 (R1R2 = H, alkyl, aryl),-SO3R (R = H, alkyl anyl),-OR (R = alkyl anyl),-NHCOR (R = H, alkyl, aryl),-OCOR (R = H, alkyl, aryl), -CONR1R2 (R1R2 = H, alkyl, aryl), -NR1R2 (R1R2 = alkyl, aryl), benzoyl, substituted benzoyl or alkyl carboxylic ester.  Suitable starting materials and the corresponding acids obtained are mentioned.  An example describes the corrosion effect of on samples of silicon iron suspended in the liquid and vapour phase sections of a reactor in which o-xylene in benzoic acid is oxidised at 150 DEG  in the presence of cobalt and manganese bromides.

Abstract: <PICT:1112607/C1/1> <PICT:1112607/C1/2> An apparatus for the continuous manufacture of glass in sheet form is characterized by a slit formed between a pair of spaced lips 4, 6, the upper lip 6 of which is composed of a plurality of small dampers arranged across the entire width of the slit, each damper being movable relative to each adjacent damper so that the depth of the slit can be varied across the width thereof, each damper being formed of or having the lowermost portion of a porous material so that a gas fed under pressure to the damper impinges on the molten glass passing beneath the damper.  Preferably, each damper has a heat-resisting upper portion 14 and a porous graphite lower portion 11.  A chamber 12 is formed in the portion 11 and nitrogen under pressure is fed therein so that it may percolate through the graphite and form a layer between the damper and the molten glass.  Side pieces 9, 10 of similar construction may also be used.  The molten glass then passes down an inclined graphite plane on to a bath of molten tin.  If necessary the dampers may be maintained in a chamber filled with a non-coating atmosphere.  In an alternative construction (Fig. 5, not shown), each damper has a smaller chamber 23 in the porous graphite portion and the heat-resisting steel portion may be water-cooled through pipes 24, 25. Porcelain may be used instead of graphite and air or a combustible gas in place of nitrogen.

Title: Improvements in automatic electric alarm systems
IPC: G08B23/00
Filed: 1929-11-21
Abstract: 340,383. Electric fire-alarm systems. McNEIL, A. H., St. Keverne, Handsworth Avenue, and ASSOCIATED FIRE ALARMS, Ltd., Jewin House, Redcross Street, both in London. Nov. 21, 1929, No. 35653. [Class 47 (i).] In an automatic alarm system of the kind comprising a series of temperature-sensitive or other circuit-closing devices controlling visual and audible alarms, the opposed contacts of the circuit-closing devices are arranged as links in separate circuits which normally carry a small watching current and include fault-alarm devices which come into operation should the watching current in any circuit fail. In the fire-alarm system shown, all the contacts a<2> of the circuit-closing devices a are in a common circuit c which includes the winding d of a high-resistance watching relay and derives a watching current from a battery b. The other contacts a<1> of the devices are arranged in groups in circuits g each of which includes a fire-alarm lamp i and the winding h of a high-resistance fault relay. The circuits g derive, from the battery b through a resistance e, a watching current which is insufficient to light the lamps i, but sufficient to hold the armatures h<1> of the relays h away from the fixed contacts h<2>. The contacts a<2>, a<1> are maintained at different potentials, so that the operation, by fire, of any circuit-closer a causes a rush of current in the corresponding circuit g. This lights up a lamp i, and actuates a relay f to close a circuit including a battery j and fire-alarm bell k. In case of a fault in a circuit c or g causing the watching current in that circuit to fail, a fault-alarm bell m is rung, and a fault-alarm lamp p or q is lighted, since the relays d or h will release their armatures d<1> or h<1>. The lamps p and q are lighted directly by the battery j, and the bell m is operated through a fault relay o and battery n.
